# Geotechnical Engineering Software | G& Data & AGS 4.1 Control > Geotechnical engineering software for borehole logging, laboratory results, validation and AGS 4.1 submission control — one central database from rig to signed deliverable. ## Capabilities ### C01 — Borehole and trial pit logging Field records captured against ISO 14688 / 14689 and BS 5930 description rules: strata, samples, groundwater, in-situ tests, with depth logic enforced as you type. ### C02 — Laboratory data management Classification, strength and consolidation tests tracked through their lifecycle to BS 1377 and ASTM methods, each result bound to a resolvable sample reference. ### C03 — Automated validation Four layers — data integrity, engineering logic, AGS 4.1 compliance and plausibility — run on entry. Contradictions are quarantined, never imported on trust. ### C04 — AGS 4.1 submission control Groups, headings and units checked against the schema before export, so a submission is right the first time it reaches the client's data checker. ### C05 — Logs, tables and reporting Production borehole logs, factual report tables and plots generated from approved records only, so drawings and data never diverge. ### C06 — Handwriting OCR intake Scanned field and lab sheets transcribed into structured records — including SPT blow counts per increment — and validated in the same pass. ## What makes it different - **Built for submissions, not spreadsheets** — Most geotechnical software stores data. G& governs it: every value carries its source, standard version and the engineer who accepted it. - **Standards-aware by default** — AGS 4.1, ISO 14688 / 14689, BS 5930, BS 1377, ASTM D1586 / D2487 and Eurocode 7 conventions are encoded in the validation rules, not left to reviewer memory. - **Legacy archives welcome** — Historic desktop archives, Excel workbooks and previously exported AGS files migrate under the same validation as live data, with provenance retained. - **Priced to be adopted** — Platform bands plus per-discipline seats, with free viewer access so reviewers and clients can read data without buying a licence. ## Questions ### What is geotechnical engineering software? Software that captures, validates, stores and reports subsurface investigation data — borehole and trial pit logs, in-situ tests, laboratory results and groundwater observations — and produces the deliverables a ground investigation is judged on, typically borehole logs, factual report tables and an AGS data submission. ### Which standards does G& support? AGS 4.1 for data exchange, ISO 14688 and ISO 14689 plus BS 5930 for soil and rock description, BS 1377 and ASTM methods for laboratory testing, ASTM D1586 and BS EN ISO 22476-3 for SPT, ASTM D2487 for classification, and Eurocode 7 conventions for derived parameters. ### Can it replace our existing geotechnical logging software? Yes. Legacy projects, templates and log layouts are migrated and rebuilt as output templates, and both systems can run in parallel while the archive is transferred, so no live works are interrupted. ### Does it handle laboratory data as well as field data? Laboratory testing runs as its own governed lifecycle — scheduling, assignment, result entry, checking and approval — bound back to the sample it came from, so field and lab data stay reconciled. ### Who uses it on a project? Site engineers and loggers capture field data, laboratory staff enter test results, a lead geotechnical engineer validates and accepts records, and consultants or owners review approved data and submissions through free viewer access. ### Is it cloud-based? Yes. Data is held in one central project database accessible to the whole delivery chain, with role-based permissions and a full audit trail against every value.
